MEAT-CURIN G INJECTOR.

Specification of Letters Patent.

Patented Mar. 8, 1921.

Application filed July 21, 1919. Serial No. 312,401.

To (1U 10 from it m up concern it known that we, FRANK Hort la Goon, of the city of Hamilton, in the county of il'entwort assist-ant superintendent, CARL "Nos: JANIELSON, of the city of Branti in the county of Brant, assistant superintendent and REDERIGK PELLING, of the ity of Brantford, in the county of Brant, draftsman, all in the Province of rio, Canada, have invented certain new useful Improvements in Meat-Curing injectors, of which the following is the spepification.

Uur invention relates to improvements 1n meat curing injectors and the object of the invention to devise means for injecting pickling fluid while under pressure into meats for the p rpose of curing the same it consists essentially of the arrange and construction oi parts as hereinl more particularly explained. V igure 1 is a plan view of our injector.

2 is a longitudinal section through 3 is a side elevation of our injector. 4 1s a sectional view on line 4-4,

indicates a cylinder provided vith leads 2 ant inc head 2 is provided with t valve bore and the head 3 with a valve 6. The head 2 is also provided with an inlet orifice 7 extending from the outer end of the head into the bore the outer end of such orifice being enlarged at 8 to receive the supply pipe 9 which leads from the supply tank in which the fluid is held under pressure. The head 3 is provided with an outlet orifice 10 extending from the bore 6 and having an enlarged outer end 11 in which is secured a nozzle 12 such nozzle being preferably provided with a threaded end which is screwed into the corresponding thread formed in the interior of the orifice enlargement l1. 13 is an orifice in longitudinal alinement with the orifice 10 and extending from the diametrically opposite side of the bore 6 through the inner face of the head.

The head 2 is also provided with a curved passageway 14 leading from the orifice 15 which enters the bore 5 at a point at right angles to the orifice The head 3 is provided with a similar passageway an orifice 23 locat d at right angles to the orifice 13 in the bore 6. The inner ends of the passages 14 and 16 are connected together by a pipe l7. 18 is a valve plug turnably held within the bore 5 and provided with a passageway 19 adapted to connect the orifices 7 and 15 together to form continuous passageway between the supply pipe 9 and passageway 14. 20 is the stem of the valve plug 18. 21 is a valve plug turnably held in the bore 6 and provided with diametrically extending passageway 22 from which extends branch passageways 23 and 24. l

In the normal position of the valve the outer end of the passageway 23 registers with the orifice 25 formed at the inner end of the passageway 1.6. The branch 24 in the normal position of the valve registers with the orifice 13 the passageway 22 having its ends closed. 26 is the stem of the valve plug 21.

27 is a lever secured to the stem 20 and 28 is a lever secured to the stem 26. The outer ends of the lovers 27 and 28 are connected together by the link rod 29. The lever 28 is provided with an outwardly extending 30. 31 is a collar which is clamped on the cylinder 1 intermediately of its length, 32- is an arm which extends from the col 1' 31 the outer end of the arm being opposite the outer portion oi the flange 30. is a tension spring connecting the arm 32 and flange together. 35 is a piston head fitted within the cylinder 1 and comprising members 36 and 37 connected together by a stem 38 which is provided with a threaded inner end 39 which passes freely through the orifices 40 in the member 37 and is secured into the orifice 41 in the member 36.

It will be noticed that the member 36 is provided with a reduced portion 42 and that the member 37 is provided with an annular flange 43 into which the extreme end of the reduced portion 42 fits. The outer face of the flange 43 is beveled outwardly at 44 and the opposing portion of the member 36 is beveled at 45 in the opposing direction. Between the beveled. portions 44 and 45 fits 1.6 and head.

the packing ring 1 :6 of suitably resilient are carried back to their normal position by material. The stem 38 of the piston extends in its normal position in proximity to the inner face ofthe head 2 thereby forming a stop limiting the movement of the piston l8 is a spiral spring extending between the piston head 36 and the inner face of the cylinder head 2. The nozzle 12 is provided with suitably arranged perforations 49 through which the pickling fluid passes with the nozzle forced into the body of meat such nozzle being provided with a pointed end to allow it to easily enter the meat.

lVhen the parts are in the position shown in the drawing the fluid enters from the supply tank through the supply pipe 9,

orifice 7, valve passage 19, orifice 15, passage 14, through the pipe 17, passage 16, orifice 25, branch passages 23 and 24 and orifice 13 into the cylinder 1 such fluid forcing the piston in the direction of arrow (see Fig. 2) against the pressure of the spring 48 until the end of the stem 38 strikes against the inner face of the cylinder head 2. WVhen this takes place the cylinder is provided 'ith a charge of fluid. The link rod 29 is then forced manually in the direction of arrow carrying such link and the arms 27 and 28 into the dotted position shown in Fig. 8. When in this position the valve plug 18 turned out of ciinen ent with the orifices 7 and. thereby cutting off the fluid ifow through the valve. Simultaneously the valve plug); 21 turned so that the passageways 23 cud 2i carried out of alinement with the ()I'lilCES 25 and 13. At the same tune,

however, the valve plug 21 is turned sul' iciently to carry the ends of the diamctrio passage 22 into longitudinal alinement with the orifices 13 and if). The fluid withthe cylinder 1 is then forced from the cylinder by means off the springs through the orifice 13, passageway 22 and oriiice 20 t the nozzle 12 and through the per- .ons l9 into the body oi meat into which the nozzle has been forced as pre viously described.

When the charge of pickling fluid has been forced into the meat the link 29 is carried back into the position shown in full lines by the tension spring 33 WhlCll has the spring 33.

From this description it will be seen that we have devised a very simple device by which pickling fluid is forced into a body of meat while under pressure so that it may thoroughly permeate the whole of such body.

Vb-at we claim as our invention is:

l. A hypodermic injector comprising a cylinder, a spring pressed piston operating therein, a supply pipe for introducing fluid under pressure into the cylinder against the face of said piston, a discharge nozzle for dispensing the fluid contents of the cylinder, and valve means. operable to establish connection between the supply pipe and the interior of the cylinder, or between the discharge nozzle and the interior of the cylinder.

2. A hypodermic injector comprising a cylinder, cylinder heads closing the ends of the cylinder, a spring pressed piston operating in said cylinder, one of said heads being provided with a valve bore and a discharge passage in communication with the interior of the cylinder, a discharge nozzle carried by said head in communication with said bore, a valve in said bore, the remaining cylinder head being provided with a valve bore having a valve therein, a supply pipe communicating with said valve bore, and a conduit extending between the first and last mentioned valve bores.

A hypodermic injector comprising a cylinder, valve heads closing the ends of said cylinder, a spring pressed piston operating in said cylinder, a supply pipe con nected to one of said heads, a conduit eX- tending between said heads and a discharge nozzle connected to the other head, the valve in one of the heads being operable to control. communication between the supply pipe and the conduit extending between the heads and the valve in the remaining head being operable to establish communication between the conduit extending between the heads and the interior of the cylinder or betw en the interior of the cylinder and the discharge nozzle.
